Reparixin in Pancreatic Islet Transplantation
Study Details
Study Description
Brief Summary
Inhibition of CXCL8 activity might represent a relevant therapeutic target to prevent injury occurring after pancreatic islet transplantation. Reparixin is a novel and specific inhibitor of CXCL8. This study is designed to explore the efficacy of reparixin in preventing graft dysfunction after islet transplantation in type 1 diabetes patients (T1D).

Detailed Description
Pancreatic islet transplantation has become a feasible option in the treatment of T1D which offers advantages over whole pancreas transplantation. However to date insulin independence can be obtained in most cases only after the patient has received repeated infusions from several donors. A non-specific immune response, mediated predominantly by innate inflammatory processes, coupled with specific cellular immune responses, possibly promoted by early inflammation, play a major role in the loss of transplanted islets from the liver. PMNs have been found to be the predominant cell types infiltrating in vitro the islets. In this regard, CXCL8 has been shown to be expressed by human islets and could play a crucial role in triggering the inflammatory reaction. Thus, CXCL8 might represent a relevant therapeutic target to prevent early graft failure. The efficacy of reparixin in improving graft outcome in mice models of intrahepatic islet transplantation, as well as the safety shown in human phase 1 and 2 studies, provide a rationale for a clinical study aimed at evaluating the effect of reparixin in preventing graft dysfunction after islet transplantation in T1D patients.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Reparixin Reparixin + Immunosuppression Reparixin was administered at a dose of 2.772 mg/kg body weight/hour for 7 days (168 hours) at each transplant. It was administered as a continuous IV infusion into a (high-flow) central vein. Investigational Product infusion was to begin approximately 12 hours (range between 6 to 16 hours) before each pancreatic islet infusion was started. The Investigator identified the time to start study drug administration. Reparixin was given to all patients of this arm using the same dosing solution (reparixin 11.00 mg/mL), but the pump rate was adjusted to provide an infusion rate of approximately 0.25 mL/kg/hour. For immunosoppression regimen see the other arm description. |

No Intervention: No experimental intervention Immunosuppression only. Induction: First islet infusion: anti-thymocyte globulin (ATG), administered IV (central vein) at the dose of 1.5 mg/kg on Day -1, 0, 1, and 2 of islet infusion. The first ATG injection was preceded by a bolus IV injection of 500 mg methylprednisolone. Induction for the second islet infusion was to be administered per center practice. Maintenance: Mycophenolate mofetil (MMF), administered orally at the dose of 1 g twice a day, starting on Day -1 of the first islet infusion; Tacrolimus, administered orally starting on Day -1 of the first islet infusion at a dose of 0.087 mg/kg twice a day. Thereafter, dosing was to be targeted to blood trough levels of 8 to 10 ng/mL. Administration continued up to Month 3 after the first transplant. Rapamycin was to replace tacrolimus from Month 3 after the first transplant. It was to be administered orally at the starting dose of 0.1 mg/kg once a day, then targeted to a blood trough level of 10 to 12 ng/mL. |
Outcome Measures
Primary Outcome Measures
- The Percentage of Insulin-independent Patients Following Single Infusion Islet Cell Transplantation at Day 75 +/- 5 [day 75 +/- 5 post-transplant]
Insulin-independence was defined as freedom from the need to take exogenous insulin for 14 or more consecutive days, with adequate glycemic control, as defined by: HbA1c level of less than 7%; glucose level after an overnight fast not exceeding 140 mg/dL (7.8 mmol/L) more than 3 times a week (based on measuring capillary glucose level a minimum of 7 times in a 7-day period); glucose level not exceeding 2-hour postprandial levels of 180 mg/dL (10 mmol/L) more than 4 times a week (based on measuring capillary glucose level a minimum of 21 times in a 7-day period).
Other Outcome Measures
- The Percentage of Insulin-independent Patients Following Islet Cell Transplantation up to One Year After the Last Transplant [up to one year after the transplant]
Insulin-independence was defined as freedom from the need to take exogenous insulin for 14 or more consecutive days, with adequate glycemic control, as defined by: HbA1c level of less than 7%; glucose level after an overnight fast not exceeding 140 mg/dL (7.8 mmol/L) more than 3 times a week (based on measuring capillary glucose level a minimum of 7 times in a 7-day period); glucose level not exceeding 2-hour postprandial levels of 180 mg/dL (10 mmol/L) more than 4 times a week (based on measuring capillary glucose level a minimum of 21 times in a 7-day period).
- Time to Achieve Insulin-independence After the Transplant 2 [up to 1 year after transplant 2]
Time to achieve insulin-independence after the transplant was defined as the number of days between islet infusion and onset of insulin-independence. This was calculated as: date of onset of insulin-independence minus the islet infusion date.
- Total Time of Insulin Independence After the Transplant [up to 1 year after transplant 2]
Total time of insulin-independence after the transplant. This was defined as the number of days between the onset and loss of insulin-independence and was calculated as the date of loss of insulin-independence minus the date of onset of insulin-independence. Of the 3 patients who achieve insulin-independence after transplant 2, only 2 remained insulin-independent up to 1 year and the mean (SD) total time of insulin-independence after the second transplant was 276 (96.2) days with a range between 208 and 344 days.
- Absolute Change in Average Daily Insulin Requirements From Pre-transplant Levels [Months 1, 3, 6, 12 post-transplant]
Daily insulin requirement was calculated as the average requirement over the previous week (seven days).
- Percentage Change in Average Daily Insulin Requirements From Pre-transplant Levels [Months 1, 3, 6, 12 post-transplant]
Daily insulin requirement was calculated as the average requirement over the previous week (seven days).
- Absolute Change in Fasted HbA1c From Pre-transplant Levels [Months 1, 3, 6, 12 post-transplant]
The absolute change between the time-point value and baseline value.
- Percentage Change in Fasted HbA1c From Pre-transplant Levels [Months 1, 3, 6, 12 post-transplant]
The absolute percentage between the time-point value and baseline value.
- The Percentage of Patients Free of Hypoglycaemic Events With Reduced Awareness [Months 1, 3, 6, 12 post-transplant]
Reduced awareness is defined as a reduced ability to recognize symptoms of hypoglycemia, sometimes referred to as "hypoglycemia unawareness".
- Number of Participants With Adverse Events by Severity and With Serious Adverse Events [up to 1 year after transplant]
Safety was assessed by monitoring the incidence and severity of adverse events (AEs) and serious AEs (SAEs) throughout the study up to 1 year after last transplant. A serious adverse event is an adverse reaction that results in death, is life-threatening, requires hospitalisation or prolongation of existing hospitalisation, results in persistent or significant disability or incapacity, or is a birth defect.
- AUC (-10 to 120 Minutes Post-dose) of Glucose Derived From Mixed Meal Tolerance Test (MMTT) at 1, 3, 6 and 12 Months Post-transplant [-10 to 120 Minutes Post-dose at Months 1, 3, 6, 12 post-transplant]
Glucose level reflects the metabolic control. The MMTT was performed after an overnight fast, at baseline (within 1 week prior to randomization), and at each of the following timepoints. AUC was calculated using the trapezoidal rule.
- AUC (-10 to 120 Minutes Post-dose) of C-peptide Derived From Mixed Meal Tolerance Test (MMTT) at 1, 3, 6 and 12 Months Post-transplant [-10 to 120 Minutes Post-dose at Months 1, 3, 6, 12 post-transplant]
C-peptide level is an indirect measure of pancreatic beta-cell function. The MMTT was performed after an overnight fast, at baseline (within 1 week prior to randomization), and at each of the following timepoints. AUC was calculated using the trapezoidal rule.
- AUC (-10 to 120 Minutes Post-dose) of Insulin Derived From Mixed Meal Tolerance Test (MMTT) at 1, 3, 6 and 12 Months Post-transplant [-10 to 120 Minutes Post-dose at Months 1, 3, 6, 12 post-transplant]
Insulin level is a direct measure of pancreatic beta-cell function. The MMTT was performed after an overnight fast, at baseline (within 1 week prior to randomization), and at each of the following timepoints. AUC was calculated using the trapezoidal rule.
- AUC(-10 to 120 Min Post Dose)/IEQ/kg for C Peptide Derived From Mixed Meal Tolerance Test (MMTT) at 1, 3, 6 Months Post-transplant 1 [-10 to 120 Minutes Post-dose at Months 1, 3, 6, 12 post-transplant]
For Transplant 1 (patients on reparixin), the mean C-Peptide AUC (derived from the MMTT) corrected by IEQ/kg values were calculated. AUC was calculated using the trapezoidal rule and normalized by the actual number of islet equivalents (IEQ) per kilo infused (IEQ/kg).
- The Percentage of Patients Free of Severe Hypoglycaemic Events [Months 1, 3, 6, 12 post-transplant]
A severe hypoglycemic event is defined as an event with one of the following symptoms: "memory loss, confusion, uncontrollable behavior, irrational behavior, unusual difficulty in awakening, suspected seizure, seizure, loss of consciousness, or visual symptoms", in which the subject was unable to treat him/herself and which was associated with either a blood glucose level <54mg/dL or prompt recovery after oral carbohydrate, i.v. glucose, or glucagon administration.
- Beta-cell Function as Assessed by Beta-score [Months 1, 3, 6, 12 post-transplant]
The beta-score provides a simple clinical scoring system that encompasses glycemic control, diabetes therapy, and endogenous insulin secretion that correlates well with physiological measures of beta-cell function. On this basis, it is suitable as an overall measure of beta-cell transplant function. Beta score is a composite scoring system based on fasting plasma glucose values, HbA1c, insulin independence or use of insulin/OHAs, and the determination of stimulated C-peptide levels. Normal values are given a score of 2, intermediate values merit a score of 1, and clearly abnormal values garner no points. Thus, a perfect score is 8, and a score of 0 indicates absolute absence of beta-cell function.
- Beta-cell Function as Assessed by TEF/IEQ/kg Ratio [At months 1, 3, 6 after transplant 1 and months 1,3, 6, and 12 after transplant 2]
The TEF/IEQ/kg ratio is a parameter to assess transplant efficiency corrected by the number of transplanted islets.
- Serum Level of Alanine Amino Transferase (ALT) [Pre-transplant and at days 1-7 and months 1 and 3 post-transplant]
ALT is commonly measured clinically as part of liver function tests.
- Serum Level of Aspartate Amino Transferase (AST) [Pre-transplant and at days 1-7 and months 1 and 3 post-transplant]
AST is commonly measured clinically as part of liver function tests.
- Change From Pre-transplant in Cytokine Levels - CXCL8 [6, 12, 24, 72, 120, and 168 hours post-transplant 1]
Time course of inflammatory chemokines/cytokines as assessed by serum levels of CXCL8 (CXC ligand 8 [formerly interleukin (IL)-8]) (time frame: 0, 6, 12, 24, 72, 120, and 168 hours after islet infusion).
- Change From Pre-transplant in Cytokine Levels - CXCL1 [6, 12, 24, 72, 120, and 168 hours post-transplant 1]
Time course of inflammatory chemokines/cytokines as assessed by serum levels of CXCL1 (time frame: 0, 6, 12, 24, 72, 120, and 168 hours after islet infusion).
- Change From Pre-transplant in Cytokine Levels - IL-6 [6, 12, 24, 72, 120, and 168 hours post-transplant 1]
Time course of inflammatory chemokines/cytokines as assessed by serum levels of interleukin 6 (IL-6) (time frame: 0, 6, 12, 24, 72, 120, and 168 hours after islet infusion).

---|---|---|
Arm/Group Description | Reparixin + Immunosuppression Reparixin was administered at a dose of 2.772 mg/kg body weight/hour for 7 days (168 hours) at each transplant. It was administered as a continuous IV infusion into a (high-flow) central vein. Investigational Product infusion was to begin approximately 12 hours (range between 6 to 16 hours) before each pancreatic islet infusion was started. The Investigator identified the time to start study drug administration. Reparixin was given to all patients of this arm using the same dosing solution (reparixin 11.00 mg/mL), but the pump rate was adjusted to provide an infusion rate of approximately 0.25 mL/kg/hour. For immunosuppression regimen see the other arm description. Reparixin: Reparixin + immunosuppression | Immunosuppression only. Induction: First islet infusion: anti-thymocyte globulin (ATG), administered IV (central vein) at the dose of 1.5 mg/kg on Day -1, 0, 1, and 2 of islet infusion. The first ATG injection was preceded by a bolus IV injection of 500 mg methylprednisolone. Induction for the second islet infusion was to be administered per center practice. Maintenance: Mycophenolate mofetil (MMF), administered orally at the dose of 1 g twice a day, starting on Day -1 of the first islet infusion; Tacrolimus, administered orally starting on Day -1 of the first islet infusion at a dose of 0.087 mg/kg twice a day. Thereafter, dosing was to be targeted to blood trough levels of 8 to 10 ng/mL. Administration continued up to Month 3 after the first transplant. Rapamycin was to replace tacrolimus from Month 3 after the first transplant. It was to be administered orally at the starting dose of 0.1 mg/kg once a day, then targeted to a blood trough level of 10 to 12 ng/mL. |

Title | Beta-cell Function as Assessed by Beta-score |
---|---|
Description | The beta-score provides a simple clinical scoring system that encompasses glycemic control, diabetes therapy, and endogenous insulin secretion that correlates well with physiological measures of beta-cell function. On this basis, it is suitable as an overall measure of beta-cell transplant function. Beta score is a composite scoring system based on fasting plasma glucose values, HbA1c, insulin independence or use of insulin/OHAs, and the determination of stimulated C-peptide levels. Normal values are given a score of 2, intermediate values merit a score of 1, and clearly abnormal values garner no points. Thus, a perfect score is 8, and a score of 0 indicates absolute absence of beta-cell function. |

Arm/Group Description | Reparixin + Immunosuppression Reparixin was administered at a dose of 2.772 mg/kg body weight/hour for 7 days (168 hours) at each transplant. It was administered as a continuous IV infusion into a (high-flow) central vein. Investigational Product infusion was to begin approximately 12 hours (range between 6 to 16 hours) before each pancreatic islet infusion was started. The Investigator identified the time to start study drug administration. Reparixin was given to all patients of this arm using the same dosing solution (reparixin 11.00 mg/mL), but the pump rate was adjusted to provide an infusion rate of approximately 0.25 mL/kg/hour. For immunosuppression regimen see the other arm description. Reparixin: Reparixin + immunosuppression | Immunosuppression only. Induction: First islet infusion: anti-thymocyte globulin (ATG), administered IV (central vein) at the dose of 1.5 mg/kg on Day -1, 0, 1, and 2 of islet infusion. The first ATG injection was preceded by a bolus IV injection of 500 mg methylprednisolone. Induction for the second islet infusion was to be administered per center practice. Maintenance: Mycophenolate mofetil (MMF), administered orally at the dose of 1 g twice a day, starting on Day -1 of the first islet infusion; Tacrolimus, administered orally starting on Day -1 of the first islet infusion at a dose of 0.087 mg/kg twice a day. Thereafter, dosing was to be targeted to blood trough levels of 8 to 10 ng/mL. Administration continued up to Month 3 after the first transplant. Rapamycin was to replace tacrolimus from Month 3 after the first transplant. It was to be administered orally at the starting dose of 0.1 mg/kg once a day, then targeted to a blood trough level of 10 to 12 ng/mL. |
